/*! \class QCPDataContainer
\brief The generic data container for one-dimensional plottables
This class template provides a fast container for data storage of one-dimensional data. The data
type is specified as template parameter (called \a DataType in the following) and must provide
some methods as described in the \ref qcpdatacontainer-datatype "next section".
The data is stored in a sorted fashion, which allows very quick lookups by the sorted key as well
as retrieval of ranges (see \ref findBegin, \ref findEnd, \ref keyRange) using binary search. The
container uses a preallocation and a postallocation scheme, such that appending and prepending
data (with respect to the sort key) is very fast and minimizes reallocations. If data is added
which needs to be inserted between existing keys, the merge usually can be done quickly too,
using the fact that existing data is always sorted. The user can further improve performance by
specifying that added data is already itself sorted by key, if he can guarantee that this is the
case (see for example \ref add(const QVector<DataType> &data, bool alreadySorted)).
The data can be accessed with the provided const iterators (\ref constBegin, \ref constEnd). If
it is necessary to alter existing data in-place, the non-const iterators can be used (\ref begin,
\ref end). Changing data members that are not the sort key (for most data types called \a key) is
safe from the container's perspective.
Great care must be taken however if the sort key is modified through the non-const iterators. For
performance reasons, the iterators don't automatically cause a re-sorting upon their
manipulation. It is thus the responsibility of the user to leave the container in a sorted state
when finished with the data manipulation, before calling any other methods on the container. A
complete re-sort (e.g. after finishing all sort key manipulation) can be done by calling \ref
sort. Failing to do so can not be detected by the container efficiently and will cause both
rendering artifacts and potential data loss.
Implementing one-dimensional plottables that make use of a \ref QCPDataContainer<T> is usually
done by subclassing from \ref QCPAbstractPlottable1D "QCPAbstractPlottable1D<T>", which
introduces an according \a mDataContainer member and some convenience methods.
\section qcpdatacontainer-datatype Requirements for the DataType template parameter
The template parameter <tt>DataType</tt> is the type of the stored data points. It must be
trivially copyable and have the following public methods, preferably inline:
\li <tt>double sortKey() const</tt>\n Returns the member variable of this data point that is the
sort key, defining the ordering in the container. Often this variable is simply called \a key.
\li <tt>static DataType fromSortKey(double sortKey)</tt>\n Returns a new instance of the data
type initialized with its sort key set to \a sortKey.
\li <tt>static bool sortKeyIsMainKey()</tt>\n Returns true if the sort key is equal to the main
key (see method \c mainKey below). For most plottables this is the case. It is not the case for
example for \ref QCPCurve, which uses \a t as sort key and \a key as main key. This is the reason
why QCPCurve unlike QCPGraph can display parametric curves with loops.
\li <tt>double mainKey() const</tt>\n Returns the variable of this data point considered the main
key. This is commonly the variable that is used as the coordinate of this data point on the key
axis of the plottable. This method is used for example when determining the automatic axis
rescaling of key axes (\ref QCPAxis::rescale).
\li <tt>double mainValue() const</tt>\n Returns the variable of this data point considered the
main value. This is commonly the variable that is used as the coordinate of this data point on
the value axis of the plottable.
\li <tt>QCPRange valueRange() const</tt>\n Returns the range this data point spans in the value
axis coordinate. If the data is single-valued (e.g. QCPGraphData), this is simply a range with
both lower and upper set to the main data point value. However if the data points can represent
multiple values at once (e.g QCPFinancialData with its \a high, \a low, \a open and \a close
values at each \a key) this method should return the range those values span. This method is used
for example when determining the automatic axis rescaling of value axes (\ref
QCPAxis::rescale).

/*! \class QCPPlottableInterface1D
\brief Defines an abstract interface for one-dimensional plottables
This class contains only pure virtual methods which define a common interface to the data
of one-dimensional plottables.
For example, it is implemented by the template class \ref QCPAbstractPlottable1D (the preferred
base class for one-dimensional plottables). So if you use that template class as base class of
your one-dimensional plottable, you won't have to care about implementing the 1d interface
yourself.
If your plottable doesn't derive from \ref QCPAbstractPlottable1D but still wants to provide a 1d
interface (e.g. like \ref QCPErrorBars does), you should inherit from both \ref
QCPAbstractPlottable and \ref QCPPlottableInterface1D and accordingly reimplement the pure
virtual methods of the 1d interface, matching your data container. Also, reimplement \ref
QCPAbstractPlottable::interface1D to return the \c this pointer.
If you have a \ref QCPAbstractPlottable pointer, you can check whether it implements this
interface by calling \ref QCPAbstractPlottable::interface1D and testing it for a non-zero return
value. If it indeed implements this interface, you may use it to access the plottable's data
without needing to know the exact type of the plottable or its data point type.

/*! \fn virtual QCPDataSelection QCPPlottableInterface1D::selectTestRect(const QRectF &rect, bool
onlySelectable) const = 0;
Returns a data selection containing all the data points of this plottable which are contained (or
hit by) \a rect. This is used mainly in the selection rect interaction for data selection (\ref
dataselection "data selection mechanism").
If \a onlySelectable is true, an empty QCPDataSelection is returned if this plottable is not
selectable (i.e. if \ref QCPAbstractPlottable::setSelectable is \ref QCP::stNone).
\note \a rect must be a normalized rect (positive or zero width and height). This is especially
important when using the rect of \ref QCPSelectionRect::accepted, which is not necessarily
normalized. Use <tt>QRect::normalized()</tt> when passing a rect which might not be normalized.

convention.
*/
/*! \fn virtual QPointF QCPPlottableInterface1D::dataPixelPosition(int index) const = 0
Returns the pixel position on the widget surface at which the data point at the given \a index
appears.
Usually this corresponds to the point of \ref dataMainKey/\ref dataMainValue, in pixel
coordinates. However, depending on the plottable, this might be a different apparent position
than just a coord-to-pixel transform of those values. For example, \ref QCPBars apparent data
values can be shifted depending on their stacking, bar grouping or configured base value.
*/
/*! \fn virtual bool QCPPlottableInterface1D::sortKeyIsMainKey() const = 0
Returns whether the sort key (\ref dataSortKey) is identical to the main key (\ref dataMainKey).

otherwise the one just above.
This can be used in conjunction with \ref findEnd to iterate over data points within a given key
range, including or excluding the bounding data points that are just beyond the specified range.
If \a expandedRange is true but there are no data points below \a sortKey, 0 is returned.
If the container is empty, returns 0 (in that case, \ref findEnd will also return 0, so a loop
using these methods will not iterate over the index 0).

/*! \fn virtual int QCPPlottableInterface1D::findEnd(double sortKey, bool expandedRange) const = 0
Returns the index one after the data point with a (sort-)key that is equal to, just above, or

considered, otherwise the one just below.
This can be used in conjunction with \ref findBegin to iterate over data points within a given
key range, including the bounding data points that are just below and above the specified range.
If \a expandedRange is true but there are no data points above \a sortKey, the index just above

/*! \class QCPAbstractPlottable1D
\brief A template base class for plottables with one-dimensional data
This template class derives from \ref QCPAbstractPlottable and from the abstract interface \ref
QCPPlottableInterface1D. It serves as a base class for all one-dimensional data (i.e. data with
one key dimension), such as \ref QCPGraph and QCPCurve.
The template parameter \a DataType is the type of the data points of this plottable (e.g. \ref
QCPGraphData or \ref QCPCurveData). The main purpose of this base class is to provide the member
\a mDataContainer (a shared pointer to a \ref QCPDataContainer "QCPDataContainer<DataType>") and
implement the according virtual methods of the \ref QCPPlottableInterface1D, such that most
subclassed plottables don't need to worry about this anymore.
Further, it provides a convenience method for retrieving selected/unselected data segments via
\ref getDataSegments. This is useful when subclasses implement their \ref draw method and need to
draw selected segments with a different pen/brush than unselected segments (also see \ref
QCPSelectionDecorator).
This class implements basic functionality of \ref QCPAbstractPlottable::selectTest and \ref
QCPPlottableInterface1D::selectTestRect, assuming point-like data points, based on the 1D data
interface. In spite of that, most plottable subclasses will want to reimplement those methods
again, to provide a more accurate hit test based on their specific data visualization geometry.
